Are you sure Newcastle will be easy to defeat Chelsea? It will be the latest match and Chelsea needs 3 points to secure their current position or to rank up to 11th place. Chelsea will try to play with their best, so Newcastle seems to get difficulty against them in this situation. Although Chelsea performance looks bad lately, we don't know how they prepare the tactic for the latest match in this season. I guess we may see a surprise in this match, it is not impossible if Chelsea can defeat Newcastle. Especially the match will be held in their home, Chelsea must try to give their best for the fans and club management.
With Chelsea's current condition, it is actually still possible for Newcastle to win by more than one goal difference in my opinion.
Even though in this match Chelsea will still continue to be determined and dominate the field as usual, but their gaps are still very much in defense especially by seeing how bad they were in yesterday's match against Manchester United in the compactness in defense.
Even though in this match Newcastle actually didn't win, that's okay, but surely they want to get 3 points as one of the conditions for increasing their performance.
Not that it looks like Chelsea will lose before the match, but with their current condition, I actually doubt that in this match they will get points.
